Shield Volcanoes
- Shield volcanoes are huge in size. - They are built by many layers of runny lava flows.
- Shield volcanoes may be produced by hot spots which lay far away from the edges of tectonic plates. -The eruptions of shield volcanoes are characterized by low-explosivity lava-fountaining that forms cinder cones and spatter cones at the vent.
